Fatal poisoning from Nicotiana glauca leaves: identification of anabasine by gas-chromatography/mass spectrometry

Death of a worker occurred after ingestion of unknown amounts of Nicotiana glauca G leaves. The leaves were cooked after having been mistakenly considered to be spices of a type which grow in Thailand. After ingestion, two Thai workers collapsed, one with asystolia. Resuscitation efforts were successful only for one of the victims. A GC/MS method was used for the identification of anabasine as the main constituent in the leaves, food extract, blood, and the urine of the deceased. Lacking a standard, it was necessary to interpret the GC/MS spectrum to identify anabasine and establish its presence.     

D1S80等位点在法医物证鉴定中应用价值评估

比较D1S80 ,DQA1+PM和CTT等位点在法医物证鉴定中应用情况 ,经研究发现 ,D1S80位点识别能力较强 ,基因遗传稳定 ,其电泳检测操作简单 ,易推广 ;DQA1+PM位点扩增片段较短 ,反向斑点杂交法灵敏度高 ,特别适用于陈旧、降解和微量生物检材的鉴定 ;CTT位点的荧光检测法稳定、可靠 ,实验结果便于保存和管理。总之 ,D1S80、DQA1+PM和CTT位点的遗传符合孟德尔定律 ,分型简便、可靠 ,在亲子鉴定和个人识别中发挥重要作用。

Mind your manners: quality of manner of death certification among medical examiners and coroners in Taiwan

To assess the quality of manner of death (MOD) certification among medical examiners/coroners (ME/Cs) in Taiwan, death certificates issued in 2002 for which the final MOD was suicide or undetermined were extracted for analysis. Indicators of the quality of MOD certification included (1) MOD not given by the ME/Cs; (2) MOD assigned by the ME/Cs was changed by the coder; (3) ratio between undetermined and suicide deaths (U/S ratio). There were 450 death certificates for which the ME/Cs did not assign the MOD in the original certificate. Three fifths (285/450) of them were issued by 4 ME/Cs. The same 4 ME/Cs also had extremely high U/S ratios (1.25-1.84) compared with the average (0.31). The overall quality of MOD certification among ME/Cs in Taiwan was fair; only a small number of ME/Cs had poor quality in MOD certification. The high U/S ratio among the 4 ME/Cs would certainly affect the suicide mortality rates of the counties the 4 ME/Cs were in charge of. Actions should be taken to improve the certification quality of these 4 ME/Cs.     

交通事故致胸、腰椎损伤致残等级评定447例分析

目的探讨车祸致胸、腰椎损伤程度与伤残程度的关系,总结伤残评定经验,探寻其规律性。方法选择胸、腰椎损伤的鉴定447例,重新审查诊断,分析治疗措施,评价胸腰部活动度丧失程度及神经功能障碍情况,分析损伤程度与后遗障碍之间的关系,综合评定伤残。结果胸、腰椎损伤类型及数量并不决定其胸、腰部活动障碍程度及神经损伤后遗症严重程度;椎体损伤的部位与胸腰部活动度障碍关系密切;神经损伤主要集中在T1至L2段脊柱损伤;椎体损伤医院误诊率较高。结论伤残评定应分析损伤与后遗症严重程度的因果关系,以损伤所致后遗症为评残依据,重点关注脊柱功能的丧失程度。     

医疗事故的原因分析和相关技术鉴定的建议

目的分析医疗事故的发生原因,及医疗纠纷技术鉴定的现状。方法32例医疗纠纷技术鉴定按一般情况(性别、年龄、主要疾病、后果)和鉴定结果(有无失误、因果关系、责任程度等)进行统计分析。结果死亡鉴定17例,活体鉴定15例。32例中医疗事故13例,非医疗事故19例,医疗事故的原因多为医疗责任心不强。结论加强医务人员综合素质培养可以减少医疗事故的发生。为了使医疗纠纷技术鉴定取得积极的效果,建议国家进一步完善有关尸体解剖的立法;事故等级中宜增加医疗差错的鉴定;有必要进一步提高医疗纠纷鉴定的公正性。     

婴幼儿猝死综合征神经病理学的研究进展

婴幼儿猝死综合征(SIDS)是指发生于1岁以内婴儿无明显病因的突然死亡,其死亡原因及鉴别诊断标准迄今仍不明确。本文参考了近年来采用免疫组化方法对SIDS神经系统病理变化的研究文献,提出SIDS致命的病理生理机制是与睡眠相关的呼吸循环失控或衰竭,即SIDS的主要病因存在于中枢神经系统,但不是单一病因。     

精神病人限定刑事责任能力评定量表在精神分裂症违法者中的运用

目的探讨《精神病人限定刑事责任能力评定量表》在精神分裂症违法者犯罪案件中的运用。方法多中心收集被评定为限定刑事责任能力的精神分裂症犯罪嫌疑人,完成量表评定,同时将限定刑事责任能力进行三级划分。结果小部分组、部分组、大部分组量表评定总分的平均分依次升高且存在显著性差异,分别为21.16±4.17、25.87±5.43、29.35±4.60;量表共18个条目均与评定分显著相关,相关系数从0.154至0.590不等;因子分析得到6个因子,能解释68.485%变异。结论精神病人限定刑事责任能力评定量表内部构建合理,在精神分裂症违法者犯罪案件中,其评定总分能有效反映三级限定刑事责任能力之间差异。
